As shown below, three layers of soil was put in a tube that is $100mm100mm$ in cross section. Water is supplied to maintain a constant head difference of $300mm$ across the sample. The coefficient of permeability of soil $1,2,$ and $3$ in the flow direction are $1{10}^{-2},3{10}^{-3},$ and $4\mathrm{.}9{10}^{-4}c\frac{m}{sec},$ respectively. Is this system safe against boiling during the water flow from point $"$a$"$ to the end of soil $3?($why$)$
